FERNDALE— The Lake County Parks & Trails Division will conduct a bird and butterfly survey on Friday, Oct. 7 from 7 to 11 a.m. at the Ferndale Preserve, located at 19220 County Road 455 in Ferndale.

Naturalists of all abilities are encouraged to help Lake County park rangers monitor the status and trends of bird populations in the preserve. Bird species expecting to make an appearance during this pivotal migration time include colorful warblers, tanagers and orioles, as they pass through on their way to the rain forests of Central and South America, or are arriving to spend the winter here in Lake County.

Also included in the survey is a count of the butterfly population that currently inhabits the preserve, which includes Checkered White, Queen and Variegated Fritillary.

The 192-acre preserve is on the western shore of Lake Apopka and has a combined equestrian and hiking trail that offers stunning vistas of Lake Apopka and the surrounding areas. The activity may include hiking over uneven or difficult terrain for a distance of over 2 miles.

It is helpful, but not necessary for participants to be able to identify most common species by sight or sound. All survey-takers must have their own binoculars and field guides, and are encouraged to bring water, snacks, sunscreen, insect repellent, a hat and hiking shoes. Space is limited, so reservations are encouraged.
